SPRING-PAD CONSTRUCTIONL Application filed se tember 20, 1924. Serial no. teases.

This invention relates to pads for pressing machines, as garment and laundry pressing machines, and has for its ObjBCt a particularly simple and efliclent sprmg construction by which destruction of thespring due to crushing beyond its elastlc l1m1t is prevented without the addition of stops.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

1n describing this invention reference 1s had to the accompanying drawings in WhlCll dike characters designate corresponding parts in all the views.

Figure 1 is a plan View, partly broken away of a preferable embodiment of my 1nvention.

Figure 2 is an enlarged vertical sectional view of such pad.

In spring pads such as are used in pressing machines, the press heads of which. are actuated by power, the springs become crushed and permanently set in crushed position in a comparatively short time, so

that, the resiliency of the springs is destroyed, and the pad is rendered useless.

y my springs, undue crushing of the springs is prevented.

Spring pads comprise generally, a base member, and an upper member or plate, and springs interposed between the said members. The springs are usually overlaid with a fabric or felt layer, and the whole enclosed in a Wrapper or fabric. This wrapper oftentimes encloses a steam chamber between the upper and lower plates.

1 designates the base member orplate, and 2 the upper member or plate, usually of felt, 3 designates a sheet as a wire mesh screen, which may be interposed between the springs and the layer 2. 4 designates the wrap er. 5 are the springs interposed between t e base plate 1 and the top memher 2. Each spring is shown as comprising a plurality of loops 6, in the form of elongated corrugations arranged one above the other, the springbeing folded from a fiat piece of spring material. Preferably the open ends 7 of the loops are narrower than the folded ends 8, so that, the sides of the loops converge toward the open ends thereof. Also preferably, the opposite or upper and lower end portions 9 and 10, are parallel or level, and thrust against the top member 2 and the base plate 1, the top portions .9 of all the springs forming a flat surface on which rests the top member. 2 or the screen 3, when used. The springs are arranged close together, so that, their upper surfaces form a substantially continuous face. Also 6 the sprin "s are arranged in rows, the; springs of one row as A, being arranged alternately or staggered with the springs B of the next row. Preferably the bottom portion 10 of each spring is an integral extension of the bottom strip 11 of the next spring, so that, the springs are formed in pairs and have their bases 10; in common. Tangs 12 may be struck from the base portions 10, and enter perforations in the base 1 for the purpose of securing the springs to the base plate 1.

Owing to this spring construction an upper continuous surface is provided, which can yield at any point, and also during compression of the springs the springs can be compressed only, untilthe open ends of the loops close, and when the open ends close the folded ends form a stiff brace or stop and prevent further crushing of the springs. Owing to this spring construction, the pad is economical in construction, and the springs are readily assembled in the pad, and provide a pad that is practically indestructible, in so far, as crushing B5 or destruction of the springs is concerned.

What 1 claim is 1. A spring for pressing machine pads, comprising a fiat strip bent upon itself to form loops, one above the other,'the open end of each loop being narrower than the opposite end of each loop 2. A spring for pressing machine pads, the sprin comprising a flat strip bent upon itself to orm a plurality of loops one above the other, each loop being reverse'ly arranged relatively to the next loop and the open end ofeach loop being narrower than the closed end and the loops being of the equal length whereby when the spring is fully compressed the closed end walls of each loop thrust against, those of the next loops.

In testimony whereof, I have hereunto signed my name, at Mohawk, in the county of Herkimer, and in the State of New York, this 30th day of August, 1924;.

ALFRED D. MAURY.
